Plug in the power adaptor and wait for the device to boot. The status LEDs on the Archer VR400 will indicate power and connection status.
Use a computer or mobile device connected to the Archer VR400 (via Ethernet or Wi‑Fi). Open a web browser and enter the default management URL (typical defaults are 192.168.1.1 or tplinkwifi.net).
Log in with the default username and password as given in the manual (often both are admin, but verify from your label). For ongoing security, change the admin password during or after the first login.
Follow the on‑screen Quick Setup wizard to configure your WAN connection. If your ISP uses PPPoE, PPPoA, or similar, enter the credentials provided by the ISP. The Archer VR400’s wizard can help select the correct mode automatically in many cases.

After these steps, the Archer VR400 should connect to the Internet, and your devices can start using the network. If you prefer, you can also tailor settings after the initial setup to optimize performance and security for your home environment.

Wireless configuration: 2.4 GHz and 5 GHz on the Archer VR400

The Archer VR400 supports two separate wireless networks to balance coverage and speed. The manual highlights the importance of choosing distinct SSIDs for each band to avoid confusion among devices. Here are practical tips:

Assign a unique SSID for 2.4 GHz and a separate SSID for 5 GHz, so you can easily connect devices to the appropriate network.
Use WPA2‑PSK security with a strong passphrase for both bands. A robust password helps protect against unauthorized access and aligns with best practices described in the manual.
Consider enabling WPS only if needed for convenience, but be aware that some security guides recommend disabling WPS to reduce a potential attack surface.
Channel selection: for interference‑free performance, you can try automatic channel selection or manually choose channels with less neighboring Wi‑Fi activity. The 5 GHz band typically has more available channels and less congestion in crowded environments.

For most households, leaving the Archer VR400 on the default wireless settings with a strong password is sufficient. If you experience dead spots, reposition the router or use the USB port for a wired access point to extend coverage subtly.

Internet connection setup and WAN options

The Archer VR400 is designed to work with DSL networks. The manual explains how to configure the WAN/DSL settings to match your ISP’s requirements. In many cases, the router will auto‑detect the correct mode, but you may need to specify parameters for PPPoE or PPPoA connections. When setting up the Internet connection on the Archer VR400:

Enter the ISP‑supplied PPPoE username and password if required by your service plan
Ensure the correct VLAN settings are applied if your provider requires them
Enable IPv6 if your network and ISP support it, to future‑proof your setup and improve online routing efficiency

The Archer VR400’s design aims to simplify the configuration while providing robust WAN options. If you experience a no‑Internet state after initial setup, revisit the WAN settings and verify credentials, line status (VDSL/ADSL), and physical connections.

Security features and best practices

Security is a cornerstone of the Archer VR400 experience. The manual emphasizes several protective measures that are quick to implement and deliver immediate benefits:
